Title: Impact release gear
IPC: B64D17/38
Filed: 1944-10-26
Abstract: 603,431. Parachute couplings. POLLARD, L. A., SMITH, W. H., and TRIANCO, Ltd. Oct. 26, 1944, No. 20893. [Class 4] [Also in Groups XXV and XXX] An article is released from suspension means (e.g. a parachute) upon impact with the ground or an abutment. Pawls 10, 11 housed in slots 12 in a connecting device 1 engage the neck 4 of a piston 2, and are blocked against releasing movement by a locking piston 7. Impact of the load with its destination effects upward movement of a plunger 19 through hydraulic transmission such as described in Specification 603,433 or through Bowden wire or lever mechanism (not shown) 'and the locking piston 7 is consequently moved upwards against the action of a spring 6. Initial movement of the locking piston 7 brings the portion 9 clear of the bottom ends 17, IS of the pawls and further movement brings the flange 8 into engagement with the tapered surfaces 15, 16 of the pawls to press the latter outwards to release the piston 2. The pressure of the spring 6 helps to move the piston 2 after its release.

[Also in Division B3] A machine for assembling mechanical parts comprises a polygonal stand 1 surmounted by a fixed polygonal turret 3, between which is placed a swivelling table 2 having a central opening, the stand and turret assembly being associated with interchangeable tools and working members, and further comprising a drive mechanism and cam members for driving the tools and working members off the drive mechanism. An electric motor drives a central shaft 12 via a reduction gear and bevel gears 13, 14 engage gears 15, 17 respectively, to drive mechanisms at the working stations located at the sides of the stand and turret. The reduction gear 7 also drives a shaft 19, which carries a plate 22. The plate is fitted with a peg 23 which engages in grooves 24 under the swivelling table 2 to form a geneva mechanism. The shaft 19 is movable axially by means of a cam 27, which engages a lever 230 pivoted to the shaft 19. The table 2 is held stationary by a dog 28 on a spring-loaded pivoted lever 29. The dog engages in the end of a groove 24 and is disengaged by the camming action of the plate 22 on the lever 29. In apparatus for assembling motor vehicle track rods, the socket 34 and ball 35 have been positioned in the housing on the rod 40 at the first three work-stations, and a spring 33 is to be positioned at a fourth station. The driven shaft 18 is journalled in bearings 37, 38 and actuating cams 44, 54, 55 are keyed thereon. The cam 44 coacts with a follower 45 carried by a lever 46, which actuates a bellcrank 51. Movement of the bell-crank moves a carriage 43 horizontally whereby a spring 33 is transferred from a support 39 to the track-rod housing by a gripping head 41 The cams 54, 55 move the head vertically and when the spring 33 is in position, the head, which includes a magnet (57), is raised while a push-rod (56) holds the spring in place until the magnet is clear, Fig. 5 (not shown). The times required to perform the work cycles at each station are substantially equal, but the longest cycle determines the time interval between successive rotary movements of the table 2.

Abstract: 1348669 Traverse cams E I DU PONT DE NEMOURS & CO 19 April 1971 [11 Feb 1970] 21439/71 Heading D1J Yarn 15 is laid on a package 7 by a camdriven traverse guide 33 such that the radius of the mid-portion (about 50%) of the yarn reversal curve varies less than 10%. The specification derives the relationship between the cam reversal curve and the resultant yarn reversal curve in terms of the "uncontrolled length" U (Fig. 3) of yarn between the guide and the package, this relationship being that the first derivative of the reversal portion of the cam track is directly proportional to the sum of the first derivative of the yarn reversal curve plus the product of the second derivative of the yarn reversal curve and the "uncontrolled length". It is also stated that, to avoid slippage of the yarn along the package at the reversal, the radius of the yarn reversal curve should be greater than the radius of the package divided by the coefficient of friction of the yarn.

Title: Separation of a mixture of paper and plastics foil
IPC: B03B9/06
Filed: 1978-05-23
Abstract: For example in domestic rubbish, the majority is composed of paper and plastic. In order to be able to separate these two portions from each other as well as possible, the rubbish mixture (4) which has been prepared in terms of size is moistened before the separation into the two portions. It has been established in this case that the later separation will be more efficient if the moistening liquid is fed to the mixture in a finely divided manner, that is for example by a spray (6), and if simultaneously with this moistening the mixture is intensively mixed, for example by means of a conveyor and mixing screw (8). The latter is situated in this case in a trough (1). Also, in this process less water than hitherto is required. <IMAGE>

Abstract: 929,703. Supporting cables. ILLINOIS TOOL WORKS Inc. June 25, 1959 [July 10, 1958], No. 21854/59. Class 36. [Also in Group XXV] A one-piece fastener made of a plastic comprises a flexible strap-like body 22, a first lateral stud 28 at or near an end of the body on which is a radially resilient shoulder facing the body, a second lateral stud 40 at or near an end of the body, which tapers to a tip and on which is a shoulder 44 facing the body, and, in or on the body a hole 46 placed to receive the second stud when the body is bent into a loop, the hole being in width greater than the tip of the second stud but less than the second stud at its shoulder and either the second stud or the wall of the hole or both being sufficiently resilient radially to enable the shoulder to be forced into the hole and then retained there. In the embodiment shown in Figs. 1 and 3 a plurality of holes 46 are provided each of which can engage the stud 40. The stud 28 has two radially resilient shoulders 30 and 32 so that it can be engaged with panels of different thicknesses; the stud 28 also has an axially extending recess 34 to facilitate collapsing of the stud during application to apertured panel. The stud 28 has a substantially oval outer peripheral surface and the recess 34 is circular in cross-section so that the stud is provided with opposite side areas having relatively thin walls which may be more readily collapsed. In a modification, Fig. 6, the stud 40a is made coaxial with the stud 28a. The second stud 40a is connected to the first stud by providing it with an extension 46 which is connected to the outer end of the first stud 28a within the recess 34a. In a modification of this construction, Fig. 9, the studs 28b and 40b are provided with a recess 34b which extends axially through both studs to facilitate collapsing of the studs during application of the fastener and to prevent radial collapsing during use a drive pin 50 is provided which is inserted into the recess 34 with a force fit. In another modification of the constructions shown in Figs. 2 and 3 the positions of the studs 40 and 28 are interchanged and the stud 40 instead of being of oval peripheral shape is of semicircular section but with a web which extends from the base of the semicircle. In a modification of this construction the stud 40 is of rectangular crosssection as are the holes 46 with which it engages. This latter construction may also be modified by arranging the stud 40 so that it is normally in line with the body but flexed to a position at right angles to the body during the use of the fastener. In a further construction, Fig. 17, the stud 28e is extended on the offset side of the body to provide a socket with a central hole 40e for receiving one of a plurality of studs 46e at the other end of the body.
